'llo illustrate one ot the uses of in v invention, lf have shown a bottle-cooling apparatus in the drawings said apparatus coniprisinpl an endless bottle carrier traveling,r 'through a housing A. lhc hottle carrier comprises a pair oit endless 'flexible traveling; supports, preterahly sprocket chains B located at the opposite sides opt the apparatus, and a series ot bottle holt (fl. The bottle holders (l are preferelilyr a rranged in unile comprising; each a transverse rovv oit bottle lll sprocket wheel D and a plurality ot smooth guidev Wheels E, said sprocket wheels and guide Wheels being so located that the bottle holders travel over an angular course within'the'housing A, as shown in Fig. l. The housing Ak is supported by a plurality ot supporting elementsF which rest upon the.. `floor. yBy referring to Fig. l it will be noted that the bottle holders C are so shaped that the bottles enter said bottle holders mouth end foremost, and when said bottles are Y traveling adjacent to the top wall ot the vide said tank into several compartments said compartments being` designated in Fig.

housing they are inverted.

designates a. suitable bottle-conveying device .bym-cans ot' which bottles are introduced into the apparatus, said bottle-conveying device beingso arranged that rows 0i bottlesare introduced mouth end foremost into the transversev` rows oli bottle holders. The bottle holders C travel in the direction r,indicated by the arrow in Fig. l, and when the bottles have passed through the apparatus and arrivent the opposite end thereoi" they are discharged trom the bottle holders onto an inclined receiving` member H provided with apivoted portion H adapted to be operated to deposit the bottles in an upright position on an endless conveyor Jby means of which said bottles are conveyed avvay from the apparatus. 'Y

Arranged within the housing il. is an elongated tank l, said ktanl; being so arranged thatV` the bottle holders travel entirely around said tank. The tank l is providral with a plurality ot vpaititions @which dil by the reference characters 3, el, 5 and VBy referring to I it will be noted that an end .Wall vot' tliecoi'npartnient 6 is inclined7 said end wall being approximately parallel with the adjacent portions ot the 1 sprocket chains B; By relterring to Fig. l it will be notedthat the partition 2 between the (lll ilow aperture 'i' in `the partition which. di-

vides the last mentioned coinpartn'ients. Bue to the absence ot an overflow aperture in the partition which divides the coinpartments 4lA and il the liquid within said compartment t will not 'find its way into the compartment 3.

t? designates a steam ipe which is ar- Leases/a ranged transversely ot the compartment il. The portion oit the steam ijnpevwliich is arranged within the compartment l is perle rated and steam is passed through said )ipe trom a suitable source and escapes into the cfnnpartmcnt El through the apertures in said pipe. rl`he steam .pipe il is provided with :i therniostatically controlled valve S) ot an \y suitable construction, which is adapted lo tuut-tion so that when the temlvnrature ol the liquid within the compartment il drops below a .predeterinined point the valve il will be opened and .steam will be introduced into said liquid. whereby the temperature thereotI will be increased. lllhcn the temperature ot the liquid within the eompartnient 3 has reached the pi'edeterniined point, the valve l) will he automaticalljY closed by the thermostatic device associated therewith and the discliargre ot :ileam trom the pipe S will be stopped. lliermostalic levices ot the type associated with the vulve l my apparatus are very well known aud may be purchased on the market, and their`- tore it is not thought to l i necessary lo de scribe same in detail, all that need be ltnovva being that a portion ol the device which is sensitive to changes in temperature is c.;- tended through a wall ol the compartment and into the liquid within said compari ment. lllhen the temperature ot the liqud within said conqartment changes `the change is telt by the portion ol the thru-nmsftatic device which extends in to said liquid, and when the change has become great enough the valve will be operated to either permit or prevent the escape oit steam into the compartment. lt is apparent, therefore. that my apparatus includes means whereby the temperature ot the liquid within the coii'qiiartment l is maintained a pproximately unitorm at all times.

Arranged within the.compartment -l is a steam pipe l() provided with perl'orations` through which steam may escape into said compartment. The compartment fl, like the conipartn'ient Il. contains a iody ol liquid, and the steam pipe has :uesociated willi i!V a thermostati ally controlled valve l whcrc-lvv the discharge ot steam 'i'voui said pipe il) ma)v be automat'icallv controlled. portion it the iliei'mostaiic device extends-l through a wall ot the compartmcnl l and into the liquid within said compartnmnt so that when the temperature ol the liquid within lhc compartment change-v sullicicntly the vulve ll will ire operated to permit or prevent the discharge et steam into the liquid within the compartment wherebf.7 the temperature olf said liquid is maintained approximately uniform at all times.

The overiiow notches termed in the walls oi the Water pan 25 are located immediately above the partition 2 which divides the comparu ments et and 5 ot the tank 1, and the over-- tioiv notches formed in the Walls ot the water pan Q6 are in'nnerliately above the partition 2 which divides the compartments 5 and G oi said tank 17 and to divide the streanfis ot water passing through said notches so that portions ot each stream will be introduced into adjacent compartments, l arrange Watei'shedding` devices 5L adjacent to said overtiow notches. r``hese water-shedding devices comprise each an inverted tf-shaped plate and each of said V- shaped plates is arranged With its apex at the approximate center of the associated notch, as shown in Fig. 11. By this arrangement the streams ot Water passing tlirough the overi'ioiv notches will be divided, portie* ot said streams passing down the oppositely inclined Walls ot said water-shed dine,` devices and being detiected to opposite sides ot the partitions liii/Then the apparati'is shown in the drawing is about to be placed in operation, steam is passed through the steam pipes 0, 10.l l2 and 13 and said steam escapes through the lieriforations in said pipes into the liquid lwithin the compartments 3, h 5 and (i. This steam is permitted to escape into said conipartinents until the liquid Within the coniigmrtnient Ei reaches the approximate tempera aturc oit 17007 the liquid within the compartment i reaches the appronin'iate 'tcnipc 'at-ure ot '1110"1 the liquid Within the conipartmei'it 5 reacties the approximate temperature oi' 1100, and the liquid within the compartment reaches the approximate temperature oit 800, and 'for the salte ot clearness it have indicated these temperatures in Fig. 1 ot the drawing. When the bodies oit' liquid reach the` temperatures indicated the apparatus is ready to be placed in operation.

The bottles pass 'from the bottle-conveying mechanism Gr into the bottle holders C and begin their passage through the apparatus, the movement oi said bottles benna` either continuous or intermittent, and when injectors to 'aeh the interiors thereot. rthe `water which is forced into the interiors ot the bottles is drawn from within the com partment by the pump lf, said pump placing said water under pressure. lt is thcretore apparent that the interiors o1" the bottles are Washed with Water at a temperature oi` approximately `1700. rihe bottles next pass over the injectors 21 associated with the con-- doctors and water troni an outside source is injected into said bottles to sterilize said bottles, this Water being,v at a temperature ot between 1800 and 2000, lt is apparent, therei'tore, that when 'the bottles pass troni the injectors 21 they are quite hot.

Water from within the compartinent i drawn therefrom by the pump section 29 and some ot this water is introduced into the water pan 241e. lhe bottoni Wall of the Water pan is provided with groups ot dis-- charge apertures and therefore7 as the bot ties pass beneath these groups of apertures, Water at a temperature ot' 1400 Will be showered on said bottles whereby the tem,- perature ot the bottles is reduced to approximately that temperature.

"Water i'roin within the compartment 5 is drawn 'therefrom by the pump section 30 and some oi' this water is introduced into the water pan Q5. This water is at a temperature of approximately 1100, but it will be remembered that some ot the Water pumped from the compartment 4i, the temperature oit' which is approximately 1li-00, is also being` introduced into the water pan 25. The reA suit ot this, therefore, is that the two streams ot Water ot dii'tere-nt temperatures are merged to produce an elongated body ot Water the ten'iperature ot which varies grad ually` from a temperature o'V approximately 1550 at one end ot the water pan to a teme perature ot approximately 1150 at the opposite end thereof. rilhe bottom Vall ot the water pau 25 is provided with groups oi discharge apertures spaced longitudinally ot said Water pan, and theretore as the bottles pass benrath said water pan said bottles encounter successive showers ot water, each ot 'which is slightly cooler than the preceding' shower ot water.

WTater trom the compartment 0 is pumped into the Water pan 2G, this Water beingat a temperature ot approirimately 800, and said water tioivs toward and merges with a stream oft water being,l pumped into the water pan 20 at the opposite end thereof, the last mentioned Water comingl trom the compartment 5 and beingl approxin'ia-teiy 1100. Here again the result will be that an elongated body ot Water will be produced the temijierature of which gradually varies :trom a ytemperature o't approximately 1050 :it one ot its ends to a temperature oic approximately llfr 850 at its opposite end. The water within the water pan 26 will escape through the groups of discharge apertures in the bottom wall thereof,v and asa result the bottles` moving through the apparatus here also will encounter successive showers of water each of which is slightly cooler than the preceding` shower of water. Y

In like manner water at a temperature of approximately 800 is pumped from the compartment 6 into the water pan 27 at one `end thereof,and water from an outside sourc-e at ai-temperature of approximately 55o is introduced into said pan 27 at the opposite end thereof. These two streams of Water flow toward each other and merge.

the result being` that an elongated body of water-is produced the temperature of which gradually varies, the teniperature of said body of'water being approximately 75D at one end and D, at the opposite end thereof. Also, this body of kwater is discharged through the apertures in the bottom wall of the `water pan and therefore the bottles encounter showers ofr water each of which is slightly cooler than the preceding shower of water.

Finally the water which is introduced into compartment27 by the pipe 47 is showered down on thebottles as they pass beneath the apertures in the bottom wall of said compartment 27, further reducing' the temper: ture of the bottles to approximately 550. It is apparent, therefore, that the temperature A of the bottles or otherarticles is gradually reduced as they pass through the apparatus so that when ythey are finally discharged from theV apparatus they may be immediately filled withrelatively cold liquid'without danger of cracking said bottles.

As already stated herein, the temperatures of the .liquid `within the compartments 3 and Kwhile'waterV at a temperature of approximately 90 is being introduced into the comy partment 6 to maintain the water therein at a temperature of approximately 800.

In addition to this the vwater will take up some of the-heat from the bottles as said water is showered over said bottles` so that the water which pours back into the. com-- partments will bel slightly hotter than it" lwas when saidr water passed through the disf .charge apertures in the bottom wallsof the water pans, although this additional heat of the water will be balanced by cooler water iiowing through the overflow apertures 7 and by the cool water flowingl into the compartment 6 from the con'ipartment Q7 of the receptacle QT. In Fig. l, l have indicated the approximate temperatures of the water issuing from the groups of apertures formed in the bottom walls of the water pans.

To preventsolid matter from paf-@snpthrough the inlet pipes 32. 37 and 4t2 to the pump sections provide the open end of each of said pipes with a suitable, screen. By merely tryingy the delivery of the coolest water to the pipe eti' it is apparent that the final temperature and all intermediate temperatures may he varied.

There a constant ilow of water into the apparatus through the pipe -l-7 and it is. of course7 necessary to provide some means for an equal amount of water to escape from the apparatus. l therefore provide the compartment Llwith an overow pipe 30 and permit water from the compartment to overflow into the compartment 5 throne-h the overflo i aperture 7 in the lriiartition between said compartments. Also, water from the compartment 5 flows through the overtiow aperture in the partition Q between the compartments it and 5 and excess water within the coii'lp'artment 4lis permitted to overflow therefrom through the overflow pipe GO. it is apparent that in this way the same water is used for successive operations and a great saving is therefore realized in the amount of water used.

6l designates an overflow pipe associated with the compartnient 3 through which excessive water placed therein through the operation of the sterilizine` ejectors 2l passes from said conipartment.
